How to import a real word network topology into OMNet++

[wubin...@163.com]

Hello:

    I want to import a real-world network topology into OMNet++. The topology is a wired backhual network in the cellular network, described by .gml file, such as in http://www.topology-zoo.org/dataset.html. Therefore, it is inappropriate to use the add-ons like sumo, which is meant for the integrations of loads or maps. I wonder does the OMNet++ has some users interfaces to convert a real-world topology into NED file?

   Thank you.
